The salts of Cu in +1 oxidation state are unstable because

Options

A. `Cu^(+)" had " 3d^(10)` configuration
B. `Cu^(+)` disproportionates easily to Cu (0) and `Cu^(2+)`
C. `Cu^(+)` disproptionates easily to `Cu^(2+)" and " Cu^(3+)`
D. `Cu^(+)` is easily reduced to `Cu^(2+)`

Answer

B

Explanation

`Cu^(+)` ions undergo disproportionation,
`2Cu^(+) to Cu^(2+)+Cu`
